Dual XGPS160 Replacement Battery 3.7V 1250mAh

Dual XGPS160 SkyPro GPS Receiver — 3.7V Li-Polymer Replacement Battery (1ICP8/36/50)

This 3.7V, 1250mAh lithium-polymer cell replaces the OEM battery in the Dual XGPS160 and XGPS160 SkyPro GPS Receiver. It restores power to the unit's GPS receiver, Bluetooth link, and display backlight. Dimensions are 50.86 × 33.50 × 8.20mm — confirm these against your existing cell before fitting.

• XGPS160 and XGPS160 SkyPro compatibility: Both models share the same battery bay dimensions, connector pinout, and charge management circuit. One cell covers both variants without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the XGPS160 platform. The onboard charge controller accepted the cell without fault codes, and the protection circuit tripped correctly at the low-voltage cutoff threshold.
• Cold-start procedure after fitting: After installing this cell, power the unit on outdoors with a clear view of the sky. The GPS must complete a cold start — expect 5 to 10 minutes for first satellite fix. Subsequent power cycles will lock on faster once almanac data is cached.

GPS accuracy reduced at low battery on the XGPS160

The XGPS160 receiver chip draws more current at full sensitivity. When battery voltage drops toward the lower end of its operating range, the unit can reduce receiver sensitivity to stay within its power budget. This shows up as a wider position scatter or slower fix updates — not a GPS signal problem, a power problem. Fitting a fresh cell and charging to 4.2V resolves it.

XGPS160 shuts off without showing a low-battery warning first

The battery indicator on the XGPS160 reads estimated charge, not real-time cell voltage. As lithium-polymer cells age, their voltage curve flattens and then drops steeply near depletion. The unit still shows one bar of charge, then hits the hardware cutoff voltage and powers off abruptly. This is not a firmware fault — it's the aged cell's voltage collapsing faster than the indicator tracks. After fitting a new cell, recalibrate the indicator by running one full charge to 4.2V before use.
